While I can't say anything useful about PG&E, net metering is problematic though. As used right now in many regions of the world, it is a large and inefficient subsidy to relatively affluent solar roof owners like you and me.
Where I live, a different regime is being introduced:
- a capacity tariff: a base grid charge, calculated based upon quarterly average peak consumption
- a feed-in rate: a wholesale rate compensation for injecting self-produced green electricity into the grid (my current rate: 0.064€/kWh)
- a retail rate by one's electricity provider (my current rate: .02869€/kWh)
- subsidies for installation of solar (up to 300€/kW peak) and storage (up to 30%)
This at least conceptually incentivises both of solar installation and peak shaving. Solar is less ridiculously profitable for me, but still a no-brainer in terms of profitability.
